[Zero keyword search hits]

The case consists of a conglomeration of files (xml, pdf, txt, doc).  I ended up indexing the 131 GB data set with 2.1.1 and running the search..  This index now provides the keyword search results.  Thanks for the replies.

[Zero keyword search hits]

Processing a 1.8.4 index containing over 1 million files using 2.0.1.1. I have tried multiple single word keyword searches all resulting in zero hits.  Using known words found within Word documents also resulted in zero hits.  The source has been re-indexed three times now.  Has anyone encountered this and is there a solution?  

Thanks
